Abstract: 962,618. Magnetic storage circuits. STANDARD TELEPHONES & CABLES Ltd. March 1, 1963 [March 6, 1962], No. 8320/63. Heading H3B. The row and column circuits of a magnetic storage matrix are connected through a transformer to a high impedance current source, and any circuit discontinuity is signalled by an indicator which responds to abnormal increase in potential across the transformer. As shown in Fig. 2, the current source comprises a transistor T1 controlled by clock pulses at terminal E, and a transformer U couples the current source to the row and column selectors. If a fault occurs, the abnormal potential at terminal A fires a transistor T2, Fig. 4, and a potential is obtained at terminal B which operates the indicator through a bi-stable trigger circuit (not shown). An R, C integrating circuit is provided to prevent faulty operation by switching transients. The indicator is released by manually resetting the trigger circuit. To facilitate location of the fault in arrangements where row and column circuits are sequentially energized under the control of counters, Fig. 6 (not shown), the counter positions are shown in an indicating device which is disconnected automatically if a fault occurs. Separate transformers may be provided for the row and column circuits, Fig. 8, the respective transformer potential terminals A1, A2 being connected through a rectifier OR gate D1, D2 to transistor T2.

Abstract: 453,444. Exchange systems. TIMMIS, A. C., Ethwood, Curzon Avenue, Beaconsfield, Buckinghamshire, and ALDRIDGE, A. J., East Dene, Ducks Hill Road, Northwood, and BARNES, E. J., 15, Graham Road, Hendon, both in Middlesex. March 18, 1935, No. 8420. [Class 40 (iv)] Subscribers on a party-line are supplied with individual carrier currents from a common point. A bridge comprising high and lowfrequency chokes HF, LF is put across the line by the hook-switch contact 1 when a subscriber calls and this by means not shown in detail starts an oscillator O1 and coupled hunting switches LF1 ... LF4. At each step the frequency generated is changed to that characteristic of a different subscriber. The currents generated pass to the party line over LF2 and filter circuits Fc. Each individual branch is terminated by an impedance equal to the characteristic impedance of the line for the frequency of the subscriber concerned, but these terminations are shunted by the transformers Q at the non-calling stations. The frequencies of non-calling subscribers are therefore reflected and cause the operation of apparatus at S1 to keep the switches LF in motion. The frequency of the calling subscriber, however, is almost wholly absorbed and the switches LF are then stopped by the apparatus at S1. Apparatus on the exchange is controlled in known manner and dialling tone modulates the selected carrier with the help of apparatus M1. Dialling, by causing intermittent reflection of the carrier, controls a relay in S1 which repeats the impulses to the exchange. Ring-back or busy tone modulates the carrier in the same way as dialling tone. An individual meter selected by LF4 is actuated when the called party replies. In the case of incoming calls, the last digit of the number steps switches F1 ... F3 to select a filter passing the frequency characterizing the wanted party and to cause the oscillator 02 to generate that frequency. This frequency passes the filter Fs at the wanted substation and after rectification at Z energizes Y to bridge the bell across the linÚ, ringing current being applied to the line through the HF choke at the carrier supplying station, Fig. 1. As an alternative, the bell may be rung by a sub-audible modulation of the carrier, or a howler consisting of a tuned reed striking a resonant plate may be operated by an audible frequency modulation. The incoming call also causes the switches LF to hunt to enable an outgoing call to be established while the incoming call is in progress. Means are provided to prevent O1 from supplying the frequency in use in the incoming call.

Title: Improvements in methods and apparatus for the production of coke
IPC: C10B57/04
Filed: 1949-03-29
Abstract: 665,311. Manufacturing coke. COMPAGNIE PAN - EUROPEENNE D'INSTALLATIONS ET D'EQUIPEMENT INDUSTRIELS SOC. A R.L. March 29, 1949 [March 30, 1948; Sept. 27, 1948], Nos. 8514/49 and 8515/49. Class 55 (i). A hard metallurgical coke is produced by heating briquettes consisting mainly of raw or partly distilled coal, the briquettes containing less than 20 per cent and preferably from 12 to 15 per cent of volatile matter, by direct contact with a heating gas, so that their temperature rises at a rate of from 6‹ to 10‹ C. per minute. The briquettes, which may consist of 80 per cent of a semi-coke, 15 per cent of finely-ground caking coal and 5 per cent of pitch, are fed into the top of a coking chamber 1 with perforate walls, which is mounted vertically in an oven A. They pass continuously down through the chamber which is divided into three zones, an upper preheating zone c, a coking zone b and a cooling zone a. Recycled fixed distillation gas, heated to between 1000‹ and 1250 C. is passed into zone b and travels transversely through the mass of briquettes in sufficient volume to give a temperature rise of the mass of 6-10‹ C. per minute. The gas, together with a second stream of the same gas from the cooling zone, then passes into the preheating zone and finally discharges from the oven to pass successively through a dust separator C, a detarrer D, a cooler E, a blower B, a second cooler F and a benzol separator G, surplus gas being withdrawn into a holder H, whilst the remainder is recirculated, part through a heater I to raise its temperature for the coking process, and a second, unheated, part through the cooling zone a wherein it cools the fully coked briquettes. In a modification, Figs. 2-4 (not shown), the hot gases leaving the oven are passed through a lowtemperature distillation retort which produces from coal fines the semi-coke required for the manufacture of the briquettes.
